Steam for Linux

How to get DRI on Kubuntu 13.04. 64 bit, with nvidia graphics drivers?

So, I installed steam, using gdebi,or normally, and I always get the message about GLX not using DRI. 32 bit glxinfo shows message "libGL error: failed to load driver: swrast".What has to be done to get it to work? I would love to send some money towards Valve, but there is not much point in it, given that I can't run it normally.Is there any official (or semi-official) howto/tutorial to get steam installed on modern, 64 bit, Linux?

@drewb: I know it's issue with OpenGL, but it doesn't manifest in any other application (mostly because all other things that I use, that use OpenGL, are 64bit).I am using nvidia driver, installed using "Jockey" (Additional Drivers, in applications menu)

Okay, you are member of "video". Thats fine. Next, please check, if you installed the 32bit libraries of Mesa -> Mesa-libGL1-32bit, libva-glx1-32bit, libxcb-glx0-32bit etc. pp.If the 32bit libraries are installed, try downloading the proprietary NVIDIA Drivers and install these. In the installation process, you will be asked whether you would like to install 32bit compatibility packages. Select "YES"Maybe this could have helped... Good luck!

As for my nvidia driver - I might reinstall it, though it will take me some time - doesn't installation from Jockey (standard tool in ubuntu to install proprietary drivers) install everything correctly (including 32bit versions?).

Anyway - will reinstall nvidia drivers based on what is available on nvidia site, and report back.

Thanks for all the help, but finally decided it's not worth it. I mean - I have everything installed from packages from (theoretically supported) ubuntu/kubuntu, yet I can't run it, unless I will work on getting some additional drivers, provided by another source, and with (probably) different, non-standard, upgrading method. It's all just not worth the hassle.
